A two-node Hyper-V cluster consists of two physical servers that work together to host and manage virtual machines. If one node experiences a hardware or system failure, the virtual machines can be moved or automatically failed over to the other node, helping reduce downtime and maintain service availability. When combined with a Synology NAS for shared storage, both Hyper-V nodes can access the virtual machine files and storage from a central location, providing a reliable and flexible virtualization environment.
This guide contains steps for setting up two NODE Clusters based on Workgroups. When Hyper-V Hosts are not joined to the domain, Microsoft Failover Cluster only supports “Quick Migration” and cannot perform Live Migration.
This guide also assumes that you have the following infrastructure Ready!
- Host1 and Host2 are installed with Windows Server 2022
- Synology Storage is accessible
- Each Host contains two Network Cards (LAN, Internal)
- Configure the LAN Interface as per your LAN subnet
- Configure Internal other subnet so Hosts can communicate with each other
- Both hosts are applied with the latest Windows patches
Hyper-V Two NODE Cluster with Synology: Walkthrough Guide
Rename Network Adapters, assign corrected IP Address
For this Lab, I’m using 192.168.70.0/24 for LAN and 192.168.170.0/24 for Internal communication.
At that moment you just need Rename Servers and set up DNS Suffix, I’m using “hacluster.local”.you can see given below in the screen shot
Hyper-V Role
Now Install Hyper-v Role on both hosts, verify that the correct adapter is selected for creating vSwitch
After Hyper-V installation, open Hyper-V Manager, rename Virtual Switch to “External”
Install the Failover Clustering feature on both Hosts
It allows the two Hyper-V hosts to:
- Work together as a single cluster.
- Detect when one host fails.
- Automatically move or restart virtual machines on the surviving host.
- Provide high availability and reduce VM downtime.
Synology Storage
Log into Synology storage, and go to SAN Manager. Create new LUN (LUN = a logical disk/storage unit provided by a SAN/NAS system.)
Create the first disk for the quorum, at least 1GBCreate the required disks that you need for the cluster.and set permissions to “Allow all” hosts.
Create a second disk for the VM storage, size dependent on the required and available in Synology set permissions to “Allow all” hosts.
There will be two disks in the SAN Manager (Storage Area Network.)
Storage Connectivity
Log into Host1 and open iSCSI initiator. Go to Target and enter IP Address of Synology storage to connect.
Connect both discovered volumes.
Open Disk Management, initialize both, and assign drive letters, format as NTFS.
Disk1 – Q:
Disk2 – N:
Open Failover cluster Manager on one of the host and Validate configuration
Add both Hosts and Press NEXT to run all tests.
Review the cluster validation report, and verify that there is no error. You can ignore warnings like “Host is not joined to the domain”
After fixing errors, “Create the cluster now using the validated node”.
Specify cluster name, subnet, and any available IP Address at the next screen.
Connect to the cluster, Add data disk to “Cluster Shared Volume”
Go to Roles, Select Virtual Machine > Create new Virtual Machine
Specify the location of the Virtual Machine as “C:\ClusterStorage\Volume1”. Install the Operating System as normal.
